This bundle is for 24x S19 Antminers or 36x Whatsminers, with 120kW heat transfer performance and all needed accessories.

DCX produces a complete immersion mining solution. A space-saving (1 sq. meter) rack system consisting of:

• 3 steel immersion mining enclosures with built-in circulation pump and heat exchanger,
• Steel rack frame with maintenance platform
• 660l of the Thermasafe R: dielectric engineered fluid,
• Immersion optimized 120kW dry cooler with adaptive fan control
• Hydraulic manifold with smart circulation pump.
• Hydraulic fittings, industrial tubing, sensors, and all needed accessories are packed on one single pallet (~1200kg | 240x130x150cm) and delivered door to door with sea or air shipment.

DCX Immersion Mining Rack System removes up to 120kW of heat from miners, even on the hot summer days (35C/95F) outside. Enclosures hold 24x S19 Antminer or 36x Whatsminer M3x and the nominal heat transfer capacity of the individual enclosure is rated at 40kW.

The dielectric fluid is a one-time purchase - it does not evaporate also non-toxic and has no smell. It circulates in a closed loop, and the whole solution works for years without specific maintenance, protecting your miners from heat, vibration, humidity, dust, and insects, giving you the possibility to overclock your miners to maximum performance. Also, you are protected from constant noise, air handling effort, and all troubles related to the mining operation. The immersion rack system is a building block for bigger solutions, so it may be upgraded to a scale-out solution.

An important element of the system is a new 120kW Immersion optimized dry cooler. 120kW unit is a universal (vertical or tabletop) platform with dimensions of 240 x 100 x 50 cm. Over 250 square meters of heat exchange area. Three standard 55-65 dB 500mm fans provide 120kW of heat transfer in 35C/95F ambient and over 150kW of heat transfer for an average 25C/77F air temperature. Equipped with an adaptive fan controller, those systems constantly adapt the speed and performance to the ambient temperature.

Note: Shipment is not included!
